[0035] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] References herein to "embodiments" or "implementations" mean that a particular feature, structure, or characteristic described in connection with the embodiments or implementations may be included in at least one embodiment of the present application.

It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0037] In this specification, for convenience, words and phrases indicating orientation or positional relationships, such as "middle," "upper," "lower," "front," "back," "vertical," "horizontal," "top," "bottom," "inside," and "outside," are used to illustrate the positional relationships of constituent elements with reference to the accompanying drawings. This is merely for the purpose of facilitating the description of this specification and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present disclosure. The positional relationships of constituent elements may be appropriately changed depending on the orientation of the constituent elements being described. Therefore, the present disclosure is not limited to the words and phrases described in the specification and may be appropriately replaced depending on the circumstances.

[0038] like Figures 1 to 3 As shown, the embodiment of the present invention provides a cleaning device, comprising: a housing 1 and a moving assembly 3 and a spray assembly 2 arranged on the housing 1; the bottom of the housing 1 has an opening 11, the spray assembly 2 includes a water inlet assembly 21 and a plurality of water spray assemblies 22, the water inlet assembly 21 is located at the top of the housing 1, and the plurality of water spray assemblies 22 are located in the opening 11 of the housing 1 and are rotatably connected to the water inlet assembly 21, wherein the water inlet assembly 21 has a rotation axis R (as shown in FIG. Figure 1 and Figure 2 The rotation axis R extends in a direction perpendicular to the opening 11 (the extension direction is shown in FIG. Figure 2 As shown in a), multiple water spray assemblies 22 can rotate around the rotation axis R of the water inlet assembly 21; wherein, the water inlet assembly 21 is provided with a water inlet channel 211, and the water spray assembly 22 is provided with a water outlet channel 221 connected to the water inlet channel 211, and the spray direction of the water spray assembly 22 is toward the opening 11.

[0039] In this embodiment, the shell 1 is an ellipsoid as a whole, with a hollow cavity inside. The bottom of the shell 1 is an opening 11 structure. The water inlet assembly 21 of the spray assembly 2 is located outside the shell 1 and can be connected to an external water source (not shown in the figure). The water spray assembly 22 of the spray assembly 2 is located in the cavity of the shell 1, and the spraying direction of the water spray assembly 22 is toward the opening 11 of the shell 1; when the cleaning device is placed on the ground, the bottom of the shell 1 coincides with the ground, so that the ground can close the opening 11 of the shell 1. When the water spray assembly 22 of the spray assembly 2 sprays water toward the ground, the water sprayed by the water spray assembly 22 will not be sprayed out from the opening 11, thereby avoiding the situation where the water spray assembly 22 causes the ground outside the shell 1 to be dirty.

[0040] Furthermore, the rotation axis R of the water inlet assembly 21 can be specifically set at the connection between each water spray assembly 22 (such as Figure 1 and Figure 2As shown), each water spray assembly 22 can rotate around the rotation axis R; a plurality of water spray assemblies 22 are arranged inside the shell 1, and the water spray assemblies 22 are rotatably connected to the water inlet assembly 21 around the rotation axis R of the water inlet assembly 21, wherein the rotation axis R of the water inlet assembly 21 extends toward the opening 11 of the shell 1, and the rotation axis R of this embodiment is preferably perpendicular to the direction of the opening 11; the water inlet assembly 21 supplies water to the plurality of water spray assemblies 22. The arrangement of the plurality of water spray assemblies 22 enables the cleaning device to have multiple water spray ends. Compared with a cleaning device with only one water spray assembly 22, the cleaning device of the present invention can shorten the distance between the respective water spray ends, thereby increasing the cleaning range of the cleaning device during cleaning and greatly improving the cleaning efficiency. Among them, multiple water spray components 22 can rotate relative to the water inlet component 21. When the water spray component 22 sprays water, since the water spray end of the water spray component 22 can generate a large water pressure, the large water pressure causes the center of gravity of the water spray component 22 to shift toward the water spray end, so that the water spray component 22 can rotate to spray water, further improving the cleaning range; at the same time, multiple water spray components 22 are set at the same height relative to the ground, so that when multiple water spray components 22 rotate at the same time, they can not interfere with each other, avoiding the water spray end of the water spray component 22 from spraying on another water spray component 22, ensuring the stability of the cleaning device.

[0041] Among them, the water inlet component 21 is provided with a water inlet channel 211, and the water spray component 22 is provided with a water outlet channel 221 connected to the water inlet channel 211. When the water inlet component 21 is connected to the external water source, water flows in the water inlet channel 211, and the water flows through the water inlet channel 211 to the water outlet channel 221 of the water spray component 22, and then the water flows through the water outlet channel 221 to the water spray end of the water spray component 22. The water spray component 22 sprays water through its own water spraying function, thereby realizing the floor washing function of the cleaning device.

[0042] It can be understood that the number of water spray assemblies 22 in the shell 1 can be set according to the size of the cavity inside the shell 1. The more water spray assemblies 22 there are, the shorter the distance between adjacent water spray ends, thereby further improving the cleaning range of the cleaning device; it should also be understood that the length of a single water spray assembly 22 itself will also affect the distance between adjacent water spray ends. If the distance between the water spray ends needs to be shorter and the cleaning range is larger, the length of the single water spray assembly 22 itself will be set shorter, which can shorten the distance between adjacent water spray ends.

[0043] Among them, the moving component 3 can support the shell 1 and can drive the shell 1 to move on the ground, so as to meet the cleaning needs of the cleaning device at different positions and improve the convenience of users in using the cleaning device.

[0044] See also Figure 4As shown, the specific structure of the water spray assembly 22 is described in detail below:

[0045] In one embodiment, the water spray assembly 22 includes a rotary joint 222, a first conduit 223 and at least one nozzle 224, one end of the rotary joint 222 is rotatably connected to the water inlet assembly 21, the other end of the rotary joint 222 is connected to the first conduit 223, and the nozzle 224 is arranged on the first conduit 223.

[0046] In this embodiment, after the water flows into the water outlet channel 221 of the water spray assembly 22, the water is sprayed out through the nozzle 224, wherein the nozzle 224 is a high-pressure nozzle 224, so that the water sprayed from the nozzle 224 generates a large water pressure when sprayed toward the ground. The large water pressure causes the center of gravity of the first conduit 223 to deviate toward the position of the nozzle 224, thereby causing the first conduit 223 to rotate through the rotary joint 222, and the first conduit 223 links the nozzle 224 to rotate, thereby increasing the spraying range of the nozzle 224.

[0047] In one embodiment, the water outlet channel 221 includes a first water outlet channel 2211 opened on the rotary joint 222 and a second water outlet channel 2212 on the first conduit 223. The first water outlet channel 2211 is connected to the water inlet channel 211 and the second water outlet channel 2212. The second water outlet channel 2212 is connected to the nozzle 224, and the nozzle 224 sprays water toward the opening 11.

[0048] In this embodiment, when the water inlet component 21 is connected to the external water source, the water flows through the water inlet channel 211 to the first water outlet channel 2211. Since the first water outlet channel 2211 is connected to the second water outlet channel 2212, the water flows from the first water outlet channel 2211 to the second water outlet channel 2212. The second water outlet channel 2212 is connected to the nozzle 224. Finally, the water is sprayed out under the action of the nozzle 224.

[0049] See also Figure 7 As shown, in one embodiment, a third water outlet channel 2223 is further provided on the rotary joint 222 , one end of the third water outlet channel 2223 is connected to the first water outlet channel 2211 and the water inlet channel 211 , and the other end of the third water outlet channel 2223 is connected to the outside of the rotary joint 222 .

[0050] In this embodiment, when the amount of water from the external water source is large and the water flow speed is fast, the amount of water entering the water inlet channel 211 and the water outlet channel 221 is relatively large. Since the amount of water sprayed out through the nozzle 224 is less than the amount of water from the external water source entering the water inlet channel 211 and the water outlet channel 221, the water flow will gather in the water inlet channel 211 and the water outlet channel 221. By opening a third water outlet channel 2223 on the rotary joint 222, it is beneficial to discharge excess water from the third water outlet channel 2223, thereby reducing the gathering of water in the water inlet channel 211 and the water outlet channel 221.

[0051] In one embodiment, the rotary joint 222 has a rotation range of 360°, and the water inlet assembly 21 is detachably connected to the rotary joint 222 .

[0052] In this embodiment, when the water pressure generated by the high-pressure nozzle 224 drives the first conduit 223 to rotate, since the rotary joint 222 can rotate 360°, it can drive the first conduit 223 to rotate 360°, allowing the nozzle 224 to spray water in a larger range and provide greater flexibility.

[0053] In one embodiment, the first conduit 223 has a central axis C perpendicular to the rotation axis R (e.g., Figure 2 As shown in FIG. 1 , the first conduit 223 extends along the length direction of the central axis C.

[0054] In this embodiment, the first conduit 223 can be a cylinder or a rectangular body. In this embodiment, it is preferably a cylinder so that the water can flow smoothly in the second water outlet channel 2212 of the first conduit 223. The first conduit 223 is detachably connected to the rotary joint 222 in the radial direction. In this embodiment, it is preferably detachably connected to the rotary joint at the midpoint of the axis of the first conduit 223 so that the nozzle 224 can better drive the first conduit 223 to rotate when spraying water.

[0055] In a more specific embodiment, two nozzles 224 are provided and are respectively located at two ends of the first conduit 223 .

[0056] In this embodiment, the provision of two nozzles 224 can provide more water outlets, thereby expanding the cleaning range and improving the cleaning efficiency. The first conduit 223 can be driven to rotate by spraying water through any one of the nozzles 224 at both ends.

[0057] It should be noted that the number of the nozzles 224 is not limited to two, and there may be a greater number of nozzles 224 , so that the first conduit 223 has more water spray outlets, thereby improving the cleaning efficiency.

[0058] In one embodiment, blocking members 225 are provided at both ends of the first conduit 223 to prevent the water in the second water outlet channel 2212 from leaking out, and the nozzle 224 is located between the two blocking members 225 .

[0059] In this embodiment, by providing blocking members 225 at both ends of the first conduit 223 , water can be blocked from flowing out of the second water outlet channel 2212 , thereby saving water and avoiding wasting water resources.

[0060] See also Figure 5 As shown, the specific structure of the water inlet component 21 is described in detail below:

[0061] In one embodiment, the water inlet assembly 21 includes a second conduit 213 and a water inlet connector 212 and multiple water outlet connectors 214 provided on the second conduit 213 . The water inlet connector 212 is connected to an external water source, and the multiple water outlet connectors 214 are respectively connected to the water spray assembly 22 .

[0062] In this embodiment, when the water inlet component 21 is connected to an external water source, the water flow can be controlled by the water inlet joint 212 to enter the water inlet channel 211 of the water inlet component 21, and the water flow is guided to the water outlet joint 214 through the second conduit 213. The water flow is discharged from the water inlet component 21 by controlling the water outlet joint 214, and the water flow flows to the water outlet channel 221 of the water spray component 22.

[0063] In a more specific embodiment, the water inlet channel 211 is opened on the second conduit 213, and the water inlet joint 212 and the water outlet joint 214 are connected through the water inlet channel 211. When the water inlet joint 212 is connected to the external water source, the water flows from the water inlet joint 212 to the water inlet channel 211, and then the water flows from the water inlet channel 211 to the water outlet joint 214, and the water outlet joint 214 introduces the water flow into the water outlet channel 221.

[0064] The shape and extension direction of the second conduit 213 are the same as those of the first conduit 223 . The specific structure may refer to the first conduit 223 and will not be described in detail here.

[0065] See also Figures 6 to 10 As shown, in a more specific embodiment, the water inlet assembly 21 further includes a connecting member 215 and a fixing member 216. The connecting member 215 is installed on the water outlet joint 214. The connecting member 215 is provided with an avoidance hole 2151, and one end of the avoidance hole 2151 is communicated with the water outlet joint 214; the fixing member 216 is installed on the housing 1 by a plurality of screws. The fixing member 216 is provided with an annular column 2162 and an annular mounting cavity 2163 is provided inside. The annular column 2162 extends from the top of the fixing member 216 inside the mounting cavity 2163, and the connecting member 215 is threadedly connected to the annular column 2162; the rotary joint 222 includes a rotary bearing 2221, a rotating portion 2222, a first retaining spring 2224 and a second retaining spring 2225 (as shown in FIG. Figure 8 and Figure 9 The first water outlet channel 2211 is opened on the rotating part 222, and one end of the rotating part 2222 is rotatably sleeved on the outer periphery of the annular column 2162 through the first water outlet channel 2211 and is located in the installation cavity 2163. The rotating bearing 2221 is sleeved on the outer periphery of the rotating part 2222, the first retaining spring 2224 is clamped on the outer periphery of the rotating part 2222, and the second retaining spring 2225 is clamped on the inner side of the fixing member 216. The top and bottom of the rotating bearing 2221 are respectively limited between the first retaining spring 2224 and the second retaining spring 2225, and the other end of the rotating part 2222 is threadedly connected to the first conduit 223; wherein the annular column 2162 has a through hole 2161 running through the top and bottom, one end of the through hole 2161 is communicated with the other end of the avoidance hole 2151, and the other end of the through hole 2161 is communicated with the first water outlet channel 2211 and the third water outlet channel 2223 of the rotating joint 222.

[0066] In one embodiment, the first conduit 223 is detachably connected to the rotary joint 222 .

[0067] In this embodiment, the first conduit 223 is detachably connected to the rotary joint 222. When the first conduit 223 is damaged and needs repair, the first conduit 223 can be detached from the rotary joint 222, thereby conveniently repairing the first conduit 223 or replacing it with a new one, thereby extending the service life of the cleaning device.

[0068] See also Figure 7 As shown, in a more specific embodiment, a regulating valve 5 is provided in the first water outlet channel 2211, which has the function of automatic flow discharge; when the water pressure in the water inlet channel 211 is high and the water pressure in the water outlet channel 221 is low, the regulating valve 5 can close the connection between the first water outlet channel 2211 and the third water outlet channel 2223, so that the water flows from the first water outlet channel 2211 to the second water outlet channel 2212; because the opening 11 of the nozzle 224 is small, the amount of water sprayed out is less than the amount of water entering the water outlet channel 221, so that the water pressure in the water outlet channel 221 continues to rise, and when the water pressure in the water outlet channel 221 is greater than the water pressure in the water inlet channel 211, the water pressure in the water outlet channel 221 enables the regulating valve 5 to open the connection between the first water outlet channel 2211 and the third water outlet channel 2223, so that the water in the water outlet channel 221 flows out through the third water outlet channel 2223, realizing the function of the cleaning device automatically discharging according to the water pressure.

[0069] See also Figure 8 and Figure 9 As shown, the specific structure of the regulating valve 5 is described in detail below:

[0070] The regulating valve 5 includes an elastic member 51, a first sealing member 52 and a second sealing member 53. The elastic member 51 is arranged in the through hole 2161 of the annular column 2162. The first sealing member 52 and the second sealing member 53 are both provided with water flow holes running through the top and the bottom. One end of the first sealing member 52 is connected to the elastic member 51, and the other end of the first sealing member 52 is connected to the third water outlet channel 2223 and the first water outlet channel 2211. The second sealing member 53 is arranged in the first water outlet channel 2211, and one end of the second sealing member 53 is connected to the third water outlet channel 2223 and the first sealing member 52. When the water pressure in the through hole 2161 is large, the elastic member 51 is elastically stretched toward the direction of the second sealing member 53 by the pressure of the water pressure. At the same time, the elastic member 51 links the first sealing member 52 to elastically stretch toward the direction of the second sealing member 53, so that the other end of the first sealing member 52 abuts against one end of the second sealing member 53. At this time, the first sealing member 52 and the second sealing member 53 are sealed. The connection between the third water outlet channel 2223 and the first water outlet channel 2211 is closed, and only the first sealing member 52 and the second sealing member 53 are connected. Water flows from the through hole 2161 of the annular column 2162 into the first sealing member 52 and the second sealing member 53, and then flows out from the second sealing member 53 to the first water outlet channel 2211, thereby preventing water from flowing out of the third water outlet channel 2223; when the water pressure in the water outlet channel 221 rises, the water pressure in the water outlet channel 221 can squeeze the first sealing member 52, so that the elastic member 51 contracts toward the through hole 2161 of the annular column 2162, so that the elastic member 51 drives the first sealing member 52 to separate from the second sealing member 53, so as to open the connection between the third water outlet channel 2223 and the first water outlet channel 2211, and then the excess water flows from the first water outlet channel 2211 to the third water outlet channel 2223, and finally flows out from the third water outlet channel 2223, realizing the function of discharging water of the cleaning device.

[0071] The water flow hole at the other end of the first sealing member 52 is configured as a stepped hole 521 so that the water flow can better squeeze the first sealing member 52 .

[0072] More specifically, the regulating valve 5 also includes a limit ring 54, which is sleeved on the outer periphery of the first seal 52 so that the first seal 52 can move in the limit ring 54, thereby reducing the friction between the first seal 52 and the through hole 2161 and improving the service life of the first seal 52.

[0073] See also Figure 1 and Figure 2 As shown, in one embodiment, a blocking member 4 is provided at the outer edge of the opening 11 at the bottom of the housing 1 to block water droplets sprayed by the water spray assembly 22 .

[0074] In this embodiment, when the bottom periphery of the shell 1 contacts the ground, the movement of the cleaning device will cause friction between the shell 1 and the ground, thereby reducing the service life of the shell 1; by providing a blocking member 4 at the outer edge of the bottom opening 11 of the shell 1, the blocking member 4 is in contact with the ground and closes the opening 11, thereby avoiding friction between the bottom of the shell 1 and the ground, so that the blocking member 4 can block the water droplets sprayed by the water spray assembly 22, ensuring the cleanliness and tidiness of the room.

[0075] In one embodiment, the moving component 3 is a plurality of rollers, and the plurality of rollers are respectively installed on the outside of the housing 1 .

[0076] In this embodiment, four rollers can be provided and installed at the four outer corners of the shell 1 respectively, so as to support the shell 1, and rely on the rolling of the rollers on the ground to drive the shell 1 to move indoors, thereby cleaning different positions in the room, greatly improving the cleaning range of the cleaning device.

[0077] The utility model provides a cleaning device with a large cleaning range. The arrangement of multiple water spray components 22 shortens the distance between each water spray end, and multiple water spray ends can be opened at the same time to clean the ground, which greatly improves the cleaning range of the ground and can clean the ground more cleanly and tidily. In addition, the shape of the cleaning device is elliptical, which has a larger installation space than the circular shape, and can install multiple water spray components 22. At the same time, driven by the moving component 3, the cleaning device can be moved arbitrarily on the ground, which greatly facilitates the use of the cleaning device for cleaning the ground.
